It is one thing to have a warranted belief that we are reading the Bible, so long as we’re reading it with cognitive faculties functioning properly in the right kind of cognitive environment. It is something entirely different to be reading the Bible and claim “God is speaking to me.” That additional claim is miles and miles away from what any rational person can conclude from the actual experience of reading the Bible itself. For that additional claim depends on the rationality of believing that all the ancient documents in the Bible are truly God’s word, that what they say about God, the nature of nature, and its workings are true, and that how one interprets them when reading them is correct. Since the rationality of claiming “God is speaking to me” depends on the rationality of accepting these other claims, it should be shown that it's rational to accept these other claims before one can rationally claim “God is speaking to me.” Until then the rational conclusion from reading the Bible is “I am reading the Bible,” not “God is speaking to me.”
